David's Battle Circuit (DBC) & David's Battle Unit (DBU)

The DBC is a Tamiya compatible battle circuit for Heng Long S&S tanks. It allows Heng Long owners to particpiate in battles using infrared "bullets" on an equal footing with Tamiya Full-Option tanks equipped with Tamiya Battle Units (TBU), complete with simulated damage affecting speed and variable weight classes. In addition, the DBC offers momentum simulation, and options to disable the "super-spin" feature and recoil while firing. A DBC requires either an Tamiya TBU, or a DBU sensor if battling is desired. A DBC is available in kit form.
There are two versions of the DBC:

DBC HL: (previously known as just the "DBC") For use with stock Heng Long Smoke&Sound electronics and radio.
DBC RC2HL: For use with the stock Heng Long Smoke&Sound ESC/sound baord, and standard 4-5 channel RC TX/RX (27mhz, 40mhz, 50mhz, 72mhz, 75mhz, 900mhz, 2.4ghz). Great for replacing the stock 27mhz radio with your own computer radio, and permits more tanks to battle together!

The DBU is a TBU compatible IR detector and hit indicator. It can be mounted on Tamiya Full Option tanks, or on DBC equipped Heng Long tanks. It is available in kit form, and requires the user to provide their own connecting and mounting hardware. Sunlight filtering or horizontal baffling is recommended for outdoor use.

For a fully operational battling tank, most users will need:

1 DBC (either model, depending on radio)
1 DBU or 1 TBU (preferred by some clubs for standarization)
1 Sound Card (optional)

Kit orders are done in batches, depending on demand, and may take several weeks if not in stock. Occasionally, an order of kits will sell out before it arrives, so ordering even when stock is not available is recommended.

Also available, assembled kits! RCTankwars offers assembled DBC-HL, DBC-RC2HL & DBU units, plus handles all service and support directly. A great way for new users to get a battle compatible tank at a cost-effective price. Contact them for more details!

Policy: Note that these units are KITS and require the assembler to have basic soldering skills and tools. A voltmeter is handy for testing.

This is a hobby/side business of mine, it make take several days for me to package an order and drop it off at the postoffice.

Due to the kit nature of these products, all sales are final!!! The end user is responsible for all assembly and testing, and any damage done to the kits during this phase. At my discretion, I may replace questionable parts. If you ask nicely, I will assist in debugging, or perform hands on testing (shipping at buyer's cost). Most users with some soldering experience can handle these kits, but if you do not agree with these policies, please do not order. You may want to consider ordering an assembled kit (see above).
Shipping costs include the cost of packaging, padding, tape, and my time/effort to fill out customs declarations and drop them off at the post office.
